The water-soluble Dramix bundles provide a homogenous distribution of high-performance steel fibres without special equipment and without considerably increasing the mixing time.
The homogenous reinforcement gives a resistance to tensile stresses at any point in the shotcrete layer
An increase of load-bearing capacity due to the redistribution of stresses
The removal of the mesh increases the bond of the shotcrete to the surface
Excellent corrosion resistance. The use of Dramix instead of mesh results in a good quality homogeneously reinforced concrete. A high degree of density and impermeability prevents the formation of water passages. Despite the eventual appearance of rust spots on the surface, no spalling will occur in the concrete. If aesthetics is a major concern a flash coat of unreinforced shotcrete can be applied
Excellent control of cracks due to shrinkage and temperature gradients
Economic Advantages
Allows the shotcrete to follow the contours resulting in a consistent thickness, which provides a significant reduction in shotcrete consumption
The use of Dramix reinforced shotcrete minimizes losses due to rebound
The elimination of the need to install mesh and the reduction in the time for which the lifting equipment is needed results in a reduction of cycle times and overall costs
The elimination of the difficult and even dangerous job of installing mesh considerably increases safety at work site
